Black mana stone? I've never seen that before. Is that like a legendary/rare verson of the manastone, or is it some sort of condition to be able to get it (I.E certain enemy defeated has a [insert percentage]% chance of dropping black manastone)
black mana stone makes it so you can merge mana stones with the black mana stone to where you can have up to like 100+ mana in one spot
whoa, cool!
